“So peaceful … wrapped next to one another they often fall sleep nose against nose,” Eklund, 40, captioned the aww-inspiring shot. “I sit for hours but somehow it feels like minutes and I just listen to their little noises.”

Added the proud new dad, “They’ve already turned gravity completely upside down for us as the new center of everything … The difficult journey here was so worth it and all happened for a reason — thank God we didn’t give up! I didn’t know I could love this much. 👸🤴”

The babies were born on Nov. 28 via surrogate, and although this is the first photo Eklund has shared of them alone, the twins have starred with their dads on social media a few times since their birth.

“We’re so in love with them. There really are no words,” Eklund captioned a Saturday snap of the beautiful family of four. “I still cry often … just looking at them, feeding them, kissing them. They’re so perfect, they really are everything. I still can’t believe it.”

Milla and Fredrik’s debut was long-awaited by their dads, who celebrated the babies on the way with a super-chic N.Y.C. baby shower and put in the advance work to stock up on clothes, shoes, stuffed animals and more.

“First day back at work after the arrival of the kids,” Eklund captioned a Monday photo of himself in a high-rise, gazing out the window at the Big Apple city skyline.
